This is what I wrote some years ago to to just this with raw files from
my camera, etc:-

#!/bin/bash

# Use the ls command to output the date and time stamp of each file
# and awk to pick out the date and time string and the filename
for datetimefilename in $(ls --time-style=+%Y%m%d%H%M%S -l *.jpg *.JPG
*.RAF *.PEF *.AVI *.WAV | awk '{ print $6$7 }')
do
  echo $datetimefilename
# Split off the file name so that I can use it for the rename operation
  origfilename=${datetimefilename:14}
  echo $origfilename
  mv $origfilename t$datetimefilename
done
